Full service facilities for all Impact Subsea sensors and systems are provided at our factory in the UK.

Sensors and systems can be returned for service or repair by our qualified engineers.

Service of a sensor will include a:

  • Check of all sensing capabilities
  • Physical check of all components
  • Cleaning of all body parts
  • Replacement of all o-rings
  • Calibration of the sensor (if requested)

To book your sensor in for a service please contact or telephone +44(0) 1224 460 850.


All Impact Subsea sensors which require calibration can be returned for calibration by our qualified engineers.

The Impact Subsea calibration laboratory is equipped with all equipment required to conduct and verify:

  • Pressure calibrations of the ISD4000 Sensor
    • Utilising a Dead Weight Tester and calibrated Atmospheric Pressure Sensor
  • AHRS calibrations of the ISA500, ISD4000, ISM3D & ISS360 sensors
    • Checking of MEMS outputs
    • Removal of MEMS BIAS

To book your sensor in for a calibration please contact or telephone +44(0) 1224 460 850.


All ‘lite’ Impact Subsea sensors can be returned for upgrade to include full AHRS capability.

This will add the Heading, Pitch and Roll sensing capability to any Impact Subsea sensor which had been purchased initially without this feature.

If you require another modification to an existing sensor, such as an alternative connector, please contact us to discuss further.
